Features:
1. Reliable three-pass and fully wet back structure.
2. Lateral-cut tube technology: increase heat efficiency.
3. Big combustion room design: increase radiated area, decrease emission of NOx, and reduce boiler cubage.
4. Big flue gas tube: reduce the resistance of smoke flow and consumption of electricity.
5. Intelligent control system: PLC and 5.7 touch panel, multi-level protections.
6. Fiberglass heat preservation: low surface temperature and heat loss.
7. Corrugated hearth: more safety and increase heat convection.
8. Multi-level sealing for flue gas chamber: no flue gas leakage.
9. Each boiler is subject to strict inspection and testing before delivery, including hydraulic pressure testing and X ray inspection.  
10. Selecting the most suitable burner to match the boiler so as to guarantee safety and reach rated output.
11. Main components, such as burners, pumps, water level meters, valves are limited to renowned brands.
12. Stainless steel plate protective cladding for surface: fine appearance and effective protection.
13. A economizer is optional and possible to save 10% fuel and decrease noise 20dB.
14. Applicable fuels: gas, oil, dual fuel.

15. Amended dimensions for export containerization to save shipping cost.
